degrees, minutes, seconds (angles of arc). These measure right ascention (left to right) and Declination (up and down)
In astronomy more than just one coordinate system is used. Each of these have a distinct purpose. For general use, most astronomers use Right Ascension and Declination. These are roughly equivalent to Longitude and Latitude respectively. The celestial equator is the same as the Earth' equator but then projected in the sky. The zero meridian is equivalent to the position of the sun on 21th March 12:00 GMT (per definition). The definition used above is useful but not really intuitive when you start with astronomy. People tend to look more to the angle of an object above the horizon. That can be used. Then the second coordinate is the azimuth angle, or the angle from north. However, because of the diurnal motion of the Earth this position is not constant. Another coordinate system used is the galactic system. Then the position of the centre of our galaxy (in the constellation of Ophicius) is used as the zero position. But this is mainly used by people interested in galaxy astronomy. One can also use our solar system as a reference frame. Then the equator of the sun is the equator and all the planets move roughly on this line, aka the equinox. This is mainly of interest when you want to calculate planetary movements in the sky. Conclusion: there is not a single coordinate system, but the first position system is the most widely used. Directly followed by the second.

absolutely! most working astronomers have a Ph.D in astronomy, the best route towards this is not to get an undergrad degree in only astronomy as it is too limiting. combine astronomy with physics to get an astrophysics degree or go for astronomy and math with several core physics courses. courses in computer science, geology, and chemistry may also be appropriate.
A pattern in which most new species appear at about the same time.
The cartesian coordinate system is the basic coordinate system people are familiar with. If you were to plot a basic X Y graph, where X and Y increase towards infinity, you are graphing in the cartesian coordinate system. There are a few other popular coordinate systems for more advanced math, but they are rarely used by most people. (polar coordinate system is common for some calculus equations)
You can use coordinate grids formapsA graphAnd lots of other things but those are the 2 most common ones.
The celestial coordinate system is exactly analogous to the terrestrial positioning system based on latitude and longitude. Terrestrial latitude ---> celestial 'declination'. Terrestrial longitude ---> celestial 'right ascension', where one 'hour' = 15 degrees.

Easting along with northing are Cartesian coordinates for a geographic point. Easting refers to the eastward-measured distance (or x-coordinate). These coordinates are most commonly associated with the Universal Transverse Mercator (UTM) coordinate system.
